dynatrac Axle Housing Upgrade - rvc - Photo 32031900

Your original JK knuckles, axleshafts, unit bearings, and brakes all bolt on to the ProRock 44. Even our aftermarket RCV Performance axleshafts fit like a glove in the new Dynatrac housing. Don't forget to smear anti-seize on the stub shaft splines, unit bearing mating surfaces, and unit bearing mounting bolts.
